1. When ordering, specify

tolerance, termination and packaging codes:

1111SQ-47NJEC

Tolerance:

G = 2% J = 5%

(Table shows stock tolerances in bold.)

Termination: E = RoHS compliant tin-silver (96.5/3.5) over copper.

Special order, added cost:

T = RoHS tin-silver-copper (95.5/4/0.5) over copper or S = non-RoHS tin-lead (63/37) over copper.

Packaging: C = 7

″ machine-ready reel. EIA-481 embossed plastic tape (600 parts per full reel).

B = Less than full reel. In tape, but not machine ready.

To have a leader and trailer added ($25 charge), use code letter C instead.

D = 13

″ machine-ready reel. EIA-481 embossed plastic tape (2500 parts per full reel). Factory order only, not stocked.

2. Inductance measured at specified test frequency, 0.1 Vrms, 0 A using an Agilent/HP 4286A LCR meter or equivalent with a Coilcraft CCF1191C test

fixture.

3. Q measured at specified test frequency, using an Agilent/HP 4291A impedance analyzer or equivalent.

4. SRF measured using an Agilent/HP 8753 network analyzer or equivalent with a Coilcraft CCF1143 test fixture.

5. Current that causes a 20°C temperature rise from 25°C ambient.

6. Electrical specifications at 25°C.

Refer to Doc 362 “Soldering Surface Mount Components” before soldering.

Terminations RoHS compliant tin-silver over copper

Environment RoHS compliant, halogen free

Weight 34 – 50 mg

Ambient temperature –40°C to +125°C with

Irms current, +125°C

to +145°C with derated current

Storage temperature Component: –40°C to +145°C.

Tape and reel packaging: –40°C to +80°C

Resistance to soldering heat Max three 40 second reflows at

Temperature Coefficient of Inductance (TCL) +5 to +70 ppm/°C

Moisture Sensitivity Level (MSL) 1 (unlimited floor life at <30°C /

85% relative humidity)

Failures in Time (FIT) / Mean Time Between Failures (MTBF)

One per billion hours / one billion hours, calculated per Telcordia SR-332

Packaging 600/7

″ reel; 2500/13″ reel; Plastic tape: 12 mm wide,

0.35 mm thick, 8 mm pocket spacing, 3.05 mm pocket depth

PCB washing Tested with pure water or alcohol only. For other

solvents, see Doc787_PCB_Washing.pdf

• Excellent Q factors – 210 at 400 MHz!

• Inductance values from 27 to 47 nH

• Flat top and bottom for reliable pick and place and mechanical

stability
